2 Claims.

This invention relates to a barbeque pit device, the general object of the' invention being to provide an adjustable frame for tting in a pit and provided with means for holding a second adjustable frame in different horizontal positions there-r in and an adjustable spit supported in the second frame, with means for rotating the spit either in a continuous manner or intermittently.

The invention also consists in certain other features of construction, combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail reference will be had to the accompanying drawings Wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a top plan view of -the invention.

Figure 2 is a section on line 2-2 of Figure 1.

Figure 3 is a fragmentary view of one corner of the mainframe.

Figure 4 is a view of the spit.

Figure 5 is a detail view of the notched part of the second frame.

Figure 6 is a fragmentary view in elevation showing how the motor casing is supported from the second frame and also showing part of the spit.

Figure '7 is a top plan view of the casing with the cover removed to show the motor and gearing.

Figure 8 is a sectional view of the intermittent movement means.

Figure 9 is a top plan view of a pit, with different types of article holding means therein.

In these drawings, the letter A indicates the main frame which is composed of the angle iron corner posts I, each having a vertical row of notches 2 in one flange thereof, and the side and end horizontally extending bars 3, each of which is formed in sections, adjustably bolted together so that the length and width of the frame can be adjusted to suit the pit in which the frame is placed. Each notch 2 had a straight bottom wall and an upper wall which ares upwardly and outwardly as shown in Figure 2. The second or spit supporting frame is shown at B and this frame is of rectangular shape and is also composed of sectional parts adjustably connected together so that the frame can be adjusted as to its Width and length. This frame B can be placed in any desired set of notches 2 to adjust the height of the frame B from the coals in the pit and its side parts are formed with straight portions to rest on the straight walls of the notches and sloping parts to engage the flaring walls of the notches. so that frame B is rmly supported in the notches of frame A, as shown in Figure 2.

A housing or casing C is supported from one end of frame B by a bracket 4 and a motor M, of any suitable type is located in the casing. A pair of stub shafts 5 and 6 is journaled in one wall of the casing and the outer end of each shaft has a socket l therein. The shaft 5 is slowly rotated, in a continuous manner, from motor M by the gearing, shown generally at 8. The shaft 9 of one of this gearing arrangement has a pinion I thereon meshing with a gear II, which is formed with a disk I2 on one face thereof, said disk having the notches I3 therein and the gear II has the pins I4 projecting from said face and arranged opposite the notches. A slotted star wheel I is attached to the inner end of shaft 6 and engages the disk and the pins I4 cooperate with the notches of the star wheel and the wheel with the notches of the disk I2 in such a manner that the star wheel and shaft 5 is given an` intermittent movement by the gear I3.

The spit is shown at S and includes a shaft I6 and the collars I'l slidably fitting on the shaft and held in adjustedposition by the set screws I8. One collar carries the long prongs I9 and the other the short prongs 20, the two sets of prongs extending towards each other. One end of the shaft has the non-circular reduced part 2l for fitting in a socket 'I and the other end is pointed, .as at 22 so that this end of the shaft can be forced through the article to be cooked. That end of frame B opposite the end to which casing C is attached has a pair of notches 23 therein, see Figure 5 and these'notches are arranged opposite the shafts 5 and 6, so that when one end of the shaft is engaging a socket in one of the shafts 5 or 6 the other end of the shaft will be engaging one of the notches 23. When the shaft is engaged with the shaft 5, it will be seen, that the spit will be slowly and continuously rotated from the motor and when the spit is engaged with the shaft 5 it will be intermittently rotated from the motor. As will be seen from Figure 1, the frame B is formed of the angle pieces 24, adjustably connected together at the sides of the frame and adjustably connected at the ends of the frame by the straight barsA 25 and one of these bars has the notches 23 therein and the other bar carries the bracket 4 which supports the casingC. Thus the width of the frame can be adjusted without substantially changing the central position of the spit.

Of course, if it is desired to pierce the article being cooked by the shaft I6 and to have the article engaged by either or both sets of prongs, then the long set must be first removed from the shaft, the shaft run through the article and then the prongs put back on the shaft. ,Howeven it will be understood that an article may be supported by either or both sets of prongs without passing the shaft through the article and the prongs can be adjusted to suit the size of the article.

Figure 9 shows a pair of grill members 28, clamped to the prongs of the spit for use in grilling articles in the pit and this gure also shows a steak grill 21 and a fry pan 2l extending over the pit.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction, combination and arrangement of the several parts, provided such changes fall within the scope of the appended claims.

What I claim and desire to protect by Letters Patent is:

1. In a device of the character described, a main frame having vertical posts formed with vertically spaced notches, an auxiliary frame of less width than the main frame extending longitudinally in said main frame with its end portions projecting from ends of the main frame, said auxiliary frame having side bars and end bars, the side bars being engaged in selected notches of said posts to support the auxiliary frame at a predetermined height, the end bars being longitudinally adjustable to permit insertion and removal of the side bars from the notches for vertical adjustment of the auxiliary frame,

detachably engaged by the adjacent end of the shaft of said spit to turn the spit.

2. In a device of the character described, a main frame, an auxiliary frame carried by said main frame and shiftable to vertically adjusted positions, said auxiliary frame having side bars and end bars, an end bar having seats spaced from each other longitudinally thereof, a bracket carried by the other end bar and projecting outwardly therefrom, a casing supported by said bracket outwardly from the auxiliary frame, a motor in said casing, a train of gearing in said casing rotated from said motor and including a driven shaft projecting from the casing toward the auxiliary frame and having a socket at its outer end, a second train of gearing in the casing rotated from the first train and including an intermittently rotated driven shaft projecting from the casing towards the auxiliary frame and having a socket at its outer end, and a spit extending longitudinally in the auxiliary frame and having a shaft rotatably mounted adjacent .one end in a selected one of said seats and having its other end removably engaged in the socket of a selected one of the driven shafts.
